Application September 2, 1958, Serial No. 758,513 2 Claims. (Cl. 158-114) This invention relates in general to new and useful improvements in burner construction, and more specifically to an improved burner for flare gases and the like.

At the present time there is being wasted in oil fields large quantities of gas, which gas is generally referred to as flare gas. It has been found that the flare gas can be used as a useful byproduct through the formation. of carbon black. In order to accomplish this, it is desirable to provide a highly efiicient burner for this particular purpose. It is therefore the primary object of this invention to provide a burner construction which is especially designed for the burner of flare gases and the like in the manufacture of carbon black. 7

Another object of this invention is to provide an improved burner construction for burning flare gases and the like, the burner construction including a 'gas distribution box which has the top thereof formed by a burner plate, the burner plate being provided with a plurality of ridges arranged generally in a rectilinear pattern to define a plurality of individual spaces, the ridges increasing the strength of the burner plate and at the same time effectively functioning to control the draft for the individual nozzles, the nozzles opening through the individual spaces in the burner plate.

Another object of this invention is to provide an improved burner construction for burning flare gases and the like, the burner construction including a gas distribution box having the top wall thereof formed by a. burner plate, the burner plate having formed therein a plurality of individual nozzles, each of the nozzles being provided with an intake tube which projects downwardly into the gas distribution box a considerable distance below the burner plate whereby gas is supplied to the individual nozzle from the main volume of the gas disposed within the gas distribution box rather than from that gas which is immediately flowing into the gas distribution box and impinging against the underside of the burner plate.

A further object of this invention is to provide an improved burner construction for burning flare gases in the manufacture of carbon black, the burner construction being of such a nature whereby the maximum yield of carbon black may be obtained therewith, the burner construction including a gas distribution box which has the top wall thereof formed by a burner plate, the burner plate having projecting upwardly from the upper surface thereof ridges arranged in rectilinear patterns to define a grid including a plurality of individual spaces, each of the spaces having projecting therethrough a nozzle, the ridges effectively controlling drafts for the individual nozzles as Well as strengthening the plate, the ridges being tubular and having communicated therewith a forced air supply, there being provided openings through the ridges for directing the air into the individual spaces to facilitate the burning of the fiare gases.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter decribed and claimed, reference being had to the accom- 2,922,470v Patented Jan. 26,

panying drawing forming a part hereof, wherein likeznumerals refer to like parts'throughout, and which:

Figure 1 is a plan view of the burner construction and shows the general details of the burner plate thereof;

Figure 2 is a side elevational view of the burner construction with a portion of the gas distribution boxbeing broken away and shown in section in order to illustrate the details of the relationship between the burner plate: and the gas distribution box; and

Figure 3 is an enlarged fragmentary sectional view.

- taken substantially upon the plane indicated by the-secs tion line 33 of Figure 1 and shows of the construction of the burner plate.

Referring now to the drawings in detail, itwill beseerr that there is illustrated the burner construction whichis the subject of this invention, the burner construction being referred to in general by the reference numeral 10: The burner construction It) includes a gas distribution box 12. which has a bottom wall 14, end walls 16 and-*18,-anc1' side walls 26 and 22. The gas distribution box 12is open at the top and is closed by a burner plate which isreferred to in general by the reference numeral 24;

In order that gas may be supplied to the gas distribution box 12, the end wall 18 is provided'adjacent its in tersection with the bottom wall 14' and in the center there+ of with a gas inlet tube 26. The gas inlet tube 26 has. connected thereto a gas supply pipe 23;

Although the gas distribution box 12 is preferably formed of sheet metal for economy purposes, for lastingqualities" the burner plate 2.4 is. formed of. cast iron. The burner plate 24 is generally rectangular in outline and includes a flat body portion 30 which has proejcting downwardly from the underside thereof a peripheral flange 32. The flange 32 is set inwardly of the boundaries of the body portion 39 and is received within the upper portion of the gas distribution box 12. This is best shown in Figure 3. The burner plate 24 is of such a size and weight whereby the engagement thereby with the upper edges of the gas distribution box 12 will provide the necessary seal. However, if a better seal is desired, suitable conventional type of sealing means may be provided.

The burner plate 24 is further rigidified and strengthened by means of a plurality of ridges 34 which project upwardly from the body portion 30 in a generally rectilinear pattern to form a grid defining a plurality of individual spaces 36, as is best shown in Figure 1.

Aligned with the center of each of the spaces 36 is a depending tube 38 which functions as an inlet tube. The

the specific details;

portion 30 and down into the interior of the gas distribution box 12. The purpose of the gas inlet tubes 38 is to assure flow of gas from the volume of the gas Within the central portion of the gas distribution box 12 as opposed to the erratic flow of gas which exists immediately below the surface of the burner plate 24. Each of the gas inlet tubes 38 has a bore 40 therethrough. Positioned in the upper portion of each of the bores 40 is a burner nozzle 42.

In addition to strengthening the burner plate 24, the individual ridges 34 have other functions. These include providing a suitable shield for the individual spaces 36 and their respective nozzles 42 so that the drafts are those desired. It will be understood that the particular grid pattern illustrated in Figure 1 has been found to be the most efficient one for the intended purpose of forming carbon black.

In order to increase the efliciency of the burning of the flue gas, each of the ridges 34 is formed tubular and has an air duct 44 formed therein. Inasmuch as the ridges 34 intersect, all of the air ducts 44 are communicated with each other. Air is supplied to the air ducts 44 through an air supply manifold 46 which has an air supply line 48 coupled thereto. The air supply manifold 46 in turn has a plurality of lead-in pipes 50 which open into the individual air ducts 44.

As is best shown in Figures 1 and 4, each of the ridges 34 has formed therein a small air outlet opening 52' which opens generally into the center of its associated space 36. The air inlet openings 52 are of sizes to provide the necessary air supply for the effective burning of the flue gas to form the carbon black.

From the foregoing, it will be readily apparent that there has been devised an extremely simple burner con struction. However, the burner construction is of such a nature whereby the most efiective burning of flue gases and the like for the purpose of producing carbon black is obtained. This is the intention of the invention and thisresult is presently being obtained. 1

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
